Title: Image recorder
Inventor: MURAOKA MASAYUKI
IPC: G03F3/10
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of abnormal noise and the peeling of a photosensitive material even if the rotating speed of a drum is increased by providing a recorder for recording images on a sheet-like member held on a rotating cylindrical member with an agitating member for agitating air in the internal space of the cylindrical member. SOLUTION: The recorder for recording the images on the sheet-like member held on the rotating cylindrical member is provided with the agitating member for agitating the air in the internal space of the cylindrical member. Namely, this device is arranged with projection members 31g formed of metals, resins, etc., within the internal space of the rotary drum 32 so as to be mounted at the center at the left end in Fig. According to such constitution, the projections of the projection members 31g agitate the air in the internal space together with the rotation of the rotary drum 31 and, therefore, the vibrating state thereof is changed and piercing wind sounds are considered to be thereby decreased.  Even more, the projection members 31g are disposed at the center of the internal space and are so constituted as not to disturb the flow of the air infiltrating from outside via suction holes 31c.

IPC: B21D7/00
Filed: 1988-05-19
Abstract: PURPOSE:To improve workability by providing at least two engaging members in a rotary driving member and arranging these engaging members so as to engage with the peripheral part of a rotary unit with a space larger than a notched width in a cut part. CONSTITUTION:A workpiece is inserted into a cut part 62 of a chuck 60 from its peripheral direction, being arranged on the center axis of the chuck 60. This workpiece, inserted and arranged, is held on the center axis by gripping members 64a, 64b advanced into the notched part 62. Thereafter in order to change a machining direction of the workpiece, a motor is driven, and the chuck 60 rotates about the center axis. Here rotary driving power to the chuck 60 is transmitted through two engaging gears 83, 84. Since these two engaging gears 83, 84 are arranged so as to be engaged with the peripheral part of the chuck 60 separating by a space larger than notched width, even when the one engaging gear is positioned in the notched part by rotating the chuck 60 in a certain direction, the other engaging gear transmits rotary driving power to the chuck 60.

Title: Pulse detection circuit
Inventor: HOSODA SHIGERU
IPC: H03K5/19
Filed: 1985-06-07
Abstract: PURPOSE:To improve the detection speed of a pulse detection circuit by applying full wave rectification to a digital data, integrating it and inputting the result to a Schmitt gate. CONSTITUTION:A digital data is inputted from input terminals 1, 2 and subjected to a full wave rectification by diodes 6, 7 of a full wave rectifier circuit. The waveform subjected to the full wave rectification is inputted to the positive input terminal of an operational amplifier 11. The output of the operational amplifier 11 is integrated by an integration circuit comprised of a resistor 12 and a capacitor 11. While the digital data is inputted to the input terminal 1, 2, the output of the integration circuit repeats change/discharge at a potential higher than a threshold voltage Vth of the Schmitt gate 14. Thus, the output of the gate 14 gives a low level to the output terminal 15. When the digital data is not inputted from the input terminals 1, 2 the output of the Schmitt gate 14 is inverted and goes to a high level and a no signal detection signal is obtained from the output terminal 15.

Title: Production of metal castings
Inventor: MORIKAWA MINORU
IPC: B22D27/04
Filed: 1978-10-06
Abstract: PURPOSE: To widen the substantial contact area and make the directional crystallization of casting alloy easy by letting the metal or alloy of a melting point lower than the casting alloy exist in the grooves on a cooling body making contact with the casting alloy then casting.  
     CONSTITUTION: Indium fine wires 3 are placed in the bottom of the grooves 2 of, e.g., a water-cooled copper plate 1 and Ni molten metal of 1570°C is poured in the mold 4 thereon. As a result, the imperfect contact part between the cooling body 1 and casting alloy is reduced and the substantical contact area is widened, due to which the relation A between the melting point arrival points of the Ni molten metal and its position from the cooling body (shown by a curve) becomes extremely effective as compared to the abovementioned relation B. This cooling method A enables the intermediate freezing speed of the mold to be improved consierably. In this way, the directional crystallization of the casting alloy is made easier.

Patent JP-S6015840-A (JP)
Title: Optical pickup
Inventor: NAKAMURA HIROYUKI
IPC: G11B7/12
Filed: 1983-07-06
Abstract: PURPOSE:To obtain an optical pickup with a low cost, high performance and a small size by increasing the number of apertures of a disc side more than the number of apertures at a semiconductor laser side so that the ratio of the number of apertures of the semiconductor laser side of an objective lens to the number of apertures of the disc side is a specified range. CONSTITUTION:Since a light irradiated from a semiconductor laser 3 is focused always onto a disc 5 by the focus control, even if the objective lens 1 moves to any positon, the luminous flux returns to the original optical path at all times. Thus, the image of the luminous flux separated by a half mirror 7 is formed to a position symmetrical to the semiconductor laser 3 at the opposite side of the half mirror 7 without fail and a normal signal is obtained. Since the ratio of the number of apertures of the object side to the image side, i.e., the magnifying power is fluctuated more or less through the objective lens 1 moved in the focus direction, the fluctuation width is increased if the ratio is too small and an aberration is produced. If too large, the optical path length from the semiconductor laser 3 to the disc 5 is longer, it results in increasing the size of the optical pickup. Let the movable range of the objective lens be + or -1mm., then the ratio of the number of apertures is 3-5 as a proper value taking the above into account.

Title: Deciding method of control signal
Inventor: UENO HISAO
IPC: H04Q9/14
Filed: 1979-09-25
Abstract: PURPOSE:To eliminate the clearing circuit by preventing the output of the control deciding circuit from producing the signal to other serial control signals until the new serial control signal is set to the shift register. CONSTITUTION:The serial control signals are applied successively to the shift register 9 based on the serial control signal received by the detector 1 and then converted into the parallel control signals to emerge at each of the outputs E-H. These outputs are applied to the inputs E-H of the control signal deciding circuit 10. For instance, if the serial signal supplied to the register 9 is 1011 and in case the control state of the subject is desired to be changed into another state, no signal is produced at the outputs d-f of the circuit 10 until the new signal e.g. 1010 is set to the register 9. As a result, the clearing circuit can be eliminated in the register 9. And if either one of the outputs d-f becomes logic 1, the output signal can be held at the outputs g and h of the holding circuit 11 although the outputs d-f all become 0. Based on the state of the outputs g and h each, the working is controlled for the loads L1 and L2 of the circuit 13 to be controlled.
